The pcDuino v1 has four green LEDs. Two are tied to ground and, hence,
illuminated by driving the output pins to a high value:
The pcDuino v1 has four green LEDs; three can be controlled from software.
Two are tied to ground and, hence, illuminated by driving the output pins
to a high value:
1. LED1 SPI0_CLK SPI0_CLK/UART5_RX/EINT23/PI11
2. LED5 IPSOUT From the PMU (not controllable by software)

These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
defined. In that case, the usage by the board port is defined in
include/board.h and src/stm32_leds.c. The LEDs are used to encode OS-related
events as follows:

other purposes by the application (Of course, all LEDs are available to the
application if CONFIG_ARCH_LEDS is not defined.
